Investigators said the two-wheeled cart was being pulled by a horse when the animal stopped responding to the reins and went down an embankment.

State police said 58-year-old Linda Gail Craver and her husband, 58-year-old David Craver, were both thrown from the cart. Linda Craver was found dead and that David Craver was taken to the hospital for treatment for undisclosed injuries, police said.
